invention, such as will enable. others skilled in the art to which itappertains to-make and use the same.

My invention has for its object to provide a simple and inexpensive, yetefficient and durable device for hoisting ensilage from pit silos andcarrying it to remote points for feeding stock; and with this generalobject in view the invention resides in the novel features ofconstruction and unique combinations of parts to be hereinafter fullydescribed and claimed, the descriptive matter being supplemented by theaccompanying drawings which form a part of this specification and inwhich:

Figure l is a vertical section of a pit silo showing my invention inconnection therewith;

Fig. 2 is a perspective View of the device with the hoisting box inreadiness to pass onto the elevated tracks; and

Fig. 3 is a perspective View showing the manner in which the box istilted to discharge its load.

In the drawings above briefly described the numeral 1 designates a pitsilo whose top 2 is formed with a preferably rectangular opening 3, saidsilo extending several feet above the ground. One edge of the opening 3is flush with one side of the silo as shown.

A derrick frame 4: is provided above the silo, said frame including apair of standards 5 which incline from the ground to a point above theopening 3 at which point they are connected by a crown bar 6, theintermediate portions of said standards bearing against the silo as seenat 7 to assist in bracing them. Additional bracing of the standards 5 isaccomplished by brace bars 8 inclining downwardly therefrom to the top2. The crown bar 6 carries a block 9 through which a cable 10 passes,one end of said cable being secured to said block at 11 while its otherend wound on a Windlass 12 suitably supported by the brace bars 8.

Cable 10 is looped below block 9 and passes through a second block 13having a Application filed January 10, 1918. Serial 211,205;

sides of the box 17 are provided with out- Wardly projecting rollers 18located on the vertical. center-lines of said sides and slightly abovethe centers thereof. These rollers support the box 17 upona pair ofelevated rails 19 which lead from the standards 5 of the frame 4, saidrollers being guided onto said rails when the box is raised, by meansyet to be described.

The rails 19 are located along the upper edges of a pair of parallelopenwork fence structures 20 which form the sides of a. feed hunk of anysuitable length. The loaded box is pushed along the rails 19 and tiltedat intervals to discharge the ensilage into the bunk from which thestock may feed, and in order to assist in the tilting operations, a rope21 is by preference secured to the box and passed over its top as shown.

In order to guide the rollers 18 onto the tracks 19, a pair of auxiliarytracks 22 are provided, said auxiliary tracks inclining upwardly fromthe standards 5 to the inner ends of said tracks 19, which ends projectbeyond said standards and are located above the openings 3, beingpreferably inclined slightly as shown. The tracks 22 are located in theupward path of the rollers 18 With the result that said rollers willengage their lower sides when the loaded box is I raised as shown inFig. 2, whereupon con tinued raising of the box will swing the latterrearwardly until it is free of the tracks 22. When this occurs, the boxswings in the other direction and is then in position to be pushed alongthe tracks 19 when hook 14 is released. Turning of the box as it isbeing raised is prevented by contact with the side of the silo as seenin Fig. 1.

The loaded box having once been supported on the rails 19, is pushedalong the latter and tilted when required to scatter its load along thefeed bunk (see Fig. 3). The unloaded box is then returned to the siloand by engaging link 15 with hook 14 and operating the Windlassreversely it may be lowered for another amount of ensilage.

The entire device is simple and inexpensive, yet is highly efficient anddurable and a great labor saver. Since probably the best results areobtained from the construction shown such construction is preferablyused,

1. Thecombinati'on of a vertical shaft a. hoisting; bucket movable:vertically. therein,

a cable for raising said bucket a'pair of main parallel tracks leadinglaterally from the upper end of said shaft, a lateral roller on eachofi'twoopposite sides ofsaid 'bucket 7 adapted "to roll along saidtracks, and a pair of auxiliary tracks inclining downwardlyandoutwardly. from the niner ends otsald main tracks, saidcauxiliary tracksbeing located in the upward: path of said rollerswhenthebucketisbelng raised, whereby to swingsaid bucket laterally,whereupon disengagement of, the rollers. from said auxiliary tracks willcause said bucket to swing in the other direction onto said main tracks.

, 2. A structure as specified in claim 1, the

inner; ends of said. main tracks being inclined to cause initial travelof the bucket rollers" onto the same by gravity.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses. I w crimsn REBMAN.
